KVM: riscv: Add KVM_GET_REG_LIST API support
KVM_GET_REG_LIST API will return all registers that are available to
KVM_GET/SET_ONE_REG APIs. It's very useful to identify some platform
regression issue during VM migration.
Since this API was already supported on arm64, it is straightforward
to enable it on riscv with similar code structure.
